17 Interesting car tips

17 interesting car tips, not many people know! Some don't even know the old drivers.

Since the first electric car came out a long time ago, the history of cars has gone through hundreds of years today. Nowadays, cars have entered everyone's life, so today we will talk about those little knowledge about cars together. I wonder how much you've heard.

1, it is not mandatory to turn on the turn signal when driving around the island, but the turn signal must be turned on when driving out of the island.

When cruising at 4.80km/h, the wind resistance should be overcome with 60% fuel consumption; If you can drive at a speed of 200km/h, the air resistance accounts for 85% of the total resistance of the car, which is an approximate value. Different models vary greatly, so when buying a car, don't underestimate the design; At present, the drag coefficient of cars is generally less than that of human walking upright.

5. Driving a 20km/h ordinary hatchback has about 23000J of energy, which is equivalent to the sum of muzzle kinetic energy of 15 M4 carbines shooting at the same time. In fact, the impact on pedestrians is not low, so safe driving is very important. Moreover, all kinds of car bullets in the movie are exaggerated performances. In fact, the wagon is a very thin layer of iron, which can make a hole without blowing off dust.

6. The function of the rear anti-collision steel beam is to absorb energy during low-speed collision, thus reducing the damage degree of the car body steel beam. The protection function of high-speed collision is very limited, and the front anti-collision steel beam is directly connected with the longitudinal beam of the car body, which activates the energy absorption of the car body in high-speed accidents. In high-speed collision, the front anti-collision steel beam will transfer the force to the longitudinal beam, and the longitudinal beam can collect the collision force.

7. Some cars with manual transmission can actually shift gears without stepping on the clutch, provided that the engine speed reaches a certain level.

8. In fact, Volkswagen Group owns 12 brands, including Ducati Motorcycle, Scania Heavy Truck, Lamborghini Super Run and others.

12, in an emergency, if you jump out in the direction of the car, it is difficult to survive, because the body leaving the car will land at the speed of the car because of inertia; If you jump back, the speed will be relatively offset, and the impact will be reduced when you land. In addition, if you jump forward and fall to the ground, your body will lean back, the risk of hitting the back of your head is greater, and the mortality rate is higher.

13, the smell of new cars is composed of more than 50 kinds of volatile organic compounds, many of which even the car companies themselves can't figure out the source, but some old drivers can distinguish different cars by smell, which is very powerful.

14 In fact, Lamborghini has been playing SUVs since the 1970s. The founder of Porsche is the son of the founder of Volkswagen. In fact, many people in the entire Porsche family work at the top of these two car companies.

15. Once upon a time, there were two good friends, one named Charlie Rawls and the other named Henry Royce. They are determined to make the best car in the world. Now, we call this best brand Rolls-Royce. In fact, most people think that the previous name sounds good before transliteration of the Chinese name of their own models; Moreover, Honda makes motorcycles first, and then cars; Lifan also built motorcycles before making cars. At that time, Lifan was not called Lifan, but called Hongda.

16, the first electric car in the world was invented 40 years earlier than gasoline car. 1900 electric cars were popularized in America, 1834 Thomas Davenport, an American, invented the first electric car driven by a DC car. 1884, Thomas Parker made the first mass-produced electric car in London.

Until 1920, electric vehicles have strong advantages. Until the breakthrough development of internal combustion engine technology, electric vehicles with weak power, low battery life and huge batteries were put on the market, and now electric vehicles occupy the market again. 1908, Fernando Porsche invented the first hybrid car, namely Porsche 9 1 1.

17, Hitler not only gave birth to the popular Beetle, but also was the creator of the highway that Germany was proud of. Hitler set strict standards for expressways: the four lanes are 34 meters wide, with a green belt of 5 meters in the middle, no street lamps and a reflective cement column every 200 meters. In order to prevent skid, not only the road slope should be small, but also the turning radius should be as large as possible. It is because of him that highways can be popularized all over the world.

To sum up, there are indeed many interesting stories about cars in history, which makes people sigh that the development of cars now seems to be just the opposite of that of 100 years ago. From now on, what will the development of automobiles be like in 100 years?
